To all whom it may concern:

Be it known that 1, WILLIAM A. YOUNG, a citizen of the United States, residing at Cottonwood Point, in the cou nt y of Pemiscot and State of Missouri, have invented a new and useful Nut-Lock, of which the following is a novel details of construction and combina-i tion of parts more fully hereinafterdescribed.

In the accompanying drawings, Figure l is a side elevation showing my improved device applied in use. Fig.2 is a vertical transverse section on the line 2 2'of-Fig. 1. Fig. 3 is a perspective View of the fish-plate con: stituting one of the membersof my improved device. Fig. 4 is a similar view of the lock ing-key. V

Referring to the drawings, 11 indicate the adjacent meeting ends of a pair of rail; way-rails, to the opposite sides of which and wall of the groove being downwardly and inwardly inclined.

The groove in practice receives a locking key or bar 18, the lower portion of the outer side wall of which is downwardly beveled or inclined to correspond to the inclination of the adjacent wall of the groove when the .parts are assembled, at which time'the upper edge of the key will bear against the lower edges of all of the nuts. The lower edge of the key is slightly inclined longitudinally from end to end, and the bottom of the groove 17 is correspondingly inclined. Attention is here especially directed to the fact that the key, which in the assemblage of the parts is inserted endwise into the groove, will, owing to this inclination of its lower edge and bottom of the groove, be forced upward against the overlying nuts with a wedging action and will at the same time, owing to the downward in.- clination of its outer side face and the corresponding inclination of the adjacent wall of the groove, .be forced laterally inward with a wedging action against the adjacent face of the fish-plate; Thus it will be seen that there is, through the peculiar constructionof the key and groove, a double wedging action attendant upon the driving home of the key,

which will cause the latter to bind tightlying also to facilitate removal of the key when circumstances require.

, From the foregoing it will be seen that I producea device olsimple construction which will be elficient in operation, and one which is admirably adapted for the attainment of the ends in View, and one in which the key may be inserted or removed as circumstances required without injury to any of the parts, which latter are entirely free from interlocking devices.

Having thus described my invention, what I claim is e The combination with a railway-rail, of a fish-plate, bolts securingthe plate to the rail, nuts applied to the bolts, a laterally-projecting rib carried by and extending longitudinally-ot the fish-plate beneath the nuts and having an upwardly-openinggroove,the outer tion of the key will result and the latter be Wall of the groove being downwardly and insecurely maintained in place.
